Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In children 7-12 years of age with functional abdominal pain (n=42) determine:

Aim 1 - To examine and characterize the threshold of the exposure (PK) vs. response (PD) relationship of PMO (menthol)

Aim 2 - PD of PMO as assessed by:

1. Microbiome composition (16S RNA sequencing)
2. Transit rate/contractile activity (using the SmartPill®) Aim 3 - Evaluate the potential association between PD response and clinical symptoms (abdominal pain and stooling pattern via validated diary), psychosocial distress (anxiety, depression, somatization), and characterize potential side effects (questionnaire)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

An initial single-dose PK study will be carried out. Forty-two children (n=21 per dose) will be randomized to receive approximately 10.9 mg·kg-1·d-1 of PMO or to receive approximately 18.2 mg·kg-1·d-1 (1.67-fold the median dose).

Following the single-dose PK study, a PD study will be carried out wherein the subjects will receive their assigned dose of PMO for 7 days.

At baseline (before the PK study) and after the PK study (i.e., during the PD study), subjects will keep a pain and stooling diary, collect stool for microbiome analysis, and swallow a SmartPill to measure gut motility and transit time. At baseline only, anxiety, depression, somatization will be measured. During the PD study, any side effects will be recorded.

* The child has abdominal pain that meets the definition of FAP according to pediatric Rome IV
* Ability to understand study procedures and to comply with them for the entire length of the study
* Childrens' body weights will not vary by more than 10-15 kg (so that dose per kg is comparable within the two dosing groups)

Exclusion Criteria
